Geth Package Suggestions

[MysticRyuujin]

The following PR has the following changes / suggestions.

• Move WebSocket port to 8545 - Geth has supported this for a while and it's easier to just expose a single port
• Enable graphql by default - It doesn't hurt to turn it on, and having it on make life easier for developers
• Include ws.api flags by default along with the http.api flags under EXTRA_OPTIONS
• Changes type from library to service which I think is appropriate based on the description of type from here: https://docs.dappnode.io/developers/manifest-reference
• Adds keywords to the dappnode_package.json
• Removes the 30304/udp mapping - this port is no longer used by Geth
• Replace the avatar with the actual / official go-ethereum mascot

Also new geth version v1.10.16

Feel free to cherry pick from this, I think these are all reasonable / appropriate but I also might not have the full context

First of all, very thanks for all these suggestions. We will apply some of the changes you have proposed:

• Changes type from library to service which I think is appropriate based on the description of type from here: https://docs.dappnode.io/developers/manifest-reference
• Adds keywords to the dappnode_package.json
• Removes the 30304/udp mapping - this port is no longer used by Geth

We think we would not enable the graphql by default.
These changes will be applied for the next update of the package
